Obsolete — sourcing through independent channels
Diodes Incorporated has marked the P6KE13CA-T as Obsolete. Available through independent surplus and broker channels. Quantities are lot-specific; current availability and pricing are confirmed at RFQ time.
Protection window — standoff, breakdown, clamp
This 11.1V standoff suits 12V nominal rails where the steady-state bus stays below the breakdown threshold. The 18.2V clamp ceiling protects downstream silicon rated for 20V or higher — a 12V-to-5V regulator or a 12V relay coil driver sees the surge clipped before its abs-max is reached.
Package and temperature range
Housed in a DO-204AC (DO-15) axial-lead through-hole package. The through-hole body handles the thermal pulse of a 600W surge without the board-spreading limits of a surface-mount equivalent — the lead frame and solder joint carry the heat into the PCB copper. The upper end covers under-hood automotive ambient and industrial cabinet heat soak; the lower end covers cold-start conditions without derating.
